So, let me start with some background information on my relationship currently. I have been with the love of my life for 8 months now, and everything about the relationship is great. She stays at my apartment almost every night, and everything (to me at least) is going smoothly. Now, to the problem.
My previous relationship I was in before this ended because I was cheated on. We were together for 3 years, and it was the worst thing I have ever went through in my life getting over her, but I did and moved on. However, it has really caused me to do things in the relationship now that I have normally not done in my previous relationship like read her texts, get on her facebook, etc.. A couple of months ago I read on her facebook messages from a guy going back and fourth. She gave him her number and said that when he gets in town again they need to hang out. Then in the next few messages she was talking to him about how fun it was, and how she laughed all the way home about something he said. I was hurt, and didn't know what to do or say because she doesn't know I get on her facebook. Eventually, I confronted her about it, and somehow managing not to admit that I logged on her facebook, I got answers. She told me that she didn't go to lunch with him, but they were eating in the same place for lunch and ran into each other (she was out with her family eating), and that he was a long time friend of hers that is in the military and isn't in town much. I told her that stuff like that bothered me, and that I would at least like to know if you hang out with another guy or something again. She said ok and we moved on.
A few months later I get on her facebook and she sent him messages saying that she is so sorry that she missed his call and please don't hate her. I dunno if I should be mad or sad, or nothing at all, but it really is taking a toll on me. I don't know what to do. Need some advice please. Thanks.
